Features

he Diamondback Overdrive ST is a hardtail mountain bike. Lighter than a full suspension mountain bike and faster on the uphill, hardtails are great for ripping across cross country trails. The classic geometry of the Overdrive ST emphasizes traction and straight line speed. It smooths out the trail as it rolls over uneven terrain, making it one of Diamondback’s fastest mountain bikes.

This bike is part of Diamondback's READYRIDE series. Diamondback READYRIDE bikes eliminate the usual hassle of tedious at-home bike assembly, an often-ignored process that can take hours. READYRIDE bikes are hand-built and shipped direct to you. The process is simple. You need only to re-install the front wheel and put on the seat and pedals. That’s it: just put these finishing touches on the build, pump up your tires, and go!
